Question

The units of rate of reaction and the rate constant are identical for a _________.

• A. fraction-order reaction
• B. zero-order reaction
• C. first-order reaction
• D. second-order reaction

Answer 1

The correct option is B zero-order reaction

$nA\to product$

$rate=K[A{]}^n=K[A{]}^0=K$

When n=0, then the rate is equal to K and it is only possible when n is zero.

Units of the rate constant and rate of the reaction for zero order reaction is $mol.li{t}^{-1}se{c}^{-1}$.

Hence, the correct option is $\text{B}$
